ATLAS - Backplane
The Atlas bus and board was designed by Philip Covington , N8VB. N8VB also designed the plug-in board specification for HPSDR.
The Atlas is a passive backplane that all other modules plug into. The circuit board has provision for up to six DIN41612 connectors at 0.8 inch spacing. An ATX 20 pin power connector can be placed on the board so that 12v, 5v, 3.3v etc. supplies from a standard PC power supply can be used to power the system. Since such power supplies are plentiful, both new and surplus, this neatly solves the power supply requirements. The various files for the Atlas board can be found at http://hpsdr.org/support.html The DIN connector spacing and board size have been chosen such that the backplane can be fitted into a standard PC enclosure.
TAPR is now offering an Atlas bare board and optionally a parts kit. See http://www.tapr.org/kits_atlas.html for details. Be aware that these boards are NOT an assembled unit. They are only bare boards and the purchaser will need to buy the DIN connectors and other parts to populate the board (or order the parts kit), and will need to manage the assembly of the Atlas.
Meanwhile the written ATLAS documentation is available in various languages which reflects the worldwide interest in the HPSDR project. Unfortunately Spanish is missing. Would somebody volunteer for the translation, please!
